Number of terms in maximization step for computing viterbi and posterior decoding?

I've been reading about viterbi and posterior decoding. And I understand that viterbi decoding is looking for an overall most likely explanation of the observed sequence:
whereas posterior tells us about the most likely state in some n-th step:
What I fail to understand is how many terms are there in the maximization for computing the viterbi decoding z^*. Are these k^2*N? And how many terms are there in the maximization for computing z_n^* i.e. the n-th state in a posterior decoding.
